Date Wed, 06 Nov 2013 22:26:21 GMT
Tsz Wo (Nicholas), SZE created HDFS-5470:
--------------------------------------------

             Summary: Add back trunk's reportDiff algorithm to HDFS-2832
                 Key: HDFS-5470
                 URL: https://issues.apache.org/jira/browse/HDFS-5470
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Tsz Wo (Nicholas), SZE
            Assignee: Tsz Wo (Nicholas), SZE


As reminded by [~shv] in HDFS-5464, the report diff algorithm uses less memory.  It also has
a faster running time.  We should add it back to the branch.
